4 types of product assumptions and how to test them

Product assumptions are crucial in the process of product development as they form the initial framework for decision-making by product managers. These assumptions, which can pertain to features, user behaviors, market trends, or technical feasibility, guide the iterative process of product creation and validation, helping to refine and improve products based on real-world feedback. Effectively managing these assumptions reduces uncertainty, saves resources, and accelerates time to market, making it a key aspect of risk management. Product managers must continuously challenge and validate these assumptions to ensure alignment with consumer needs and market dynamics. There are four primary types of assumptions: desirability, viability, feasibility, and usability. Each type requires specific testing methods, such as user interviews, business model reviews, technical research, and usability prototypes, to confirm their validity. By focusing on testing individual assumptions before developing solutions, product managers can make more informed decisions, enhancing the overall success and impact of product initiatives.
